I get the same problem, trying to figure it out too. I'll give you a shout if I sort it out.

He means that his settings resets after game restart. I had that for controls too but then I set my ini "Read Only" and it worked. For example I want to disable in-game music and use native voices but I have to reset these after every restart.

it is to be found in your <OS-HDD>:\Documents and settings\<Username>\My files\My Games\RedOrchestra2SP\ROGame\Config\at least that's where it can be found on winXP.i might have to make a backup of those while the game is running, as it resets the ini when the game is shut down.

update: okay, that worked. i hope it also works copying those config files into the multiplayer.
